Patented Dec. 9, 1 952 WASHING OR DRYING MACHINE Christian Oskar Rasmussen, Copenhagen, Denmark, assignor to Simplex, Copenhagen, Denmark, a Danish company Application January 21, 1947, Serial No. 723,261 In Denmark October 5, 1946 1 Claim. 1

Washing or drying machines are known which during the washing periods are provided with air circulation through the water by means of a blower fastened to the cover of the machine and forcing the air through a space between the wall of the machine and a casing inserted therein, and through the open bottom of which the air passes into the interior of the casing, whereas the drying takes place by means of a hydroextractor drum inserted in the washing machine casing and driven by means of the air blast from the said blower, when the washing water has been drained off.

The purpose of the present invention is to provide a machine with an especially effective course of flow of the air emanating from. the blower both during the washing period and during the drying period by means of simply formed and easily removable parts.

For this purpose the machine according to the invention is provided with the above mentioned hydro-extractor drum, which is of a somewhat smaller diameter than the casing and has vanes along its upper edge, and is pivoted centrally of the machine. The casing has a removable cover, fitting air-tight along the upper edge of the casing, and provided with a central opening through which the air passes to the blower.

In order during the drying periods to have the vanes of the hydro-extractor drum placed at the same level as the blower, the cover is specially formed so as to have a central countersunk part, which when the different parts of the machine are stowed away will extend into the interior of the hydro-extractor drum.

In order to ensure an effective flow of air along a smooth course from the blower to the space between the wall of the machine and the casing during the washing period, a guide plate is built into the cover of the machine to guide the air flowing from the blower, which guide-plate is spaced from the cover and guides the air during the washing periods to the space between the outer wall of the washing machine and the casing. The said guide-plate surrounds the blower and encases it, openings being provided in the guide-plate to allow the air to flow to and from the blower.

In the drawings:

Fig. 1 is a vertical section of the machine,

in the casing, when the parts are stowed when the machine is not in use.

The washing or drying machine consists of an outer, cylindrical receptacle I with removable cover 2, in the top 3 of which an electric motor 4, carrying on its downward shaft 5 a blower 6, is placed. The parts mentioned are enclosed by a. guide-plate I, fastened to the under side of the cover 2 and provided with openings I5 about the blower 6. The guide-plate 'I has a central,

countersunk part 8, and during the washing periods the guide-plate 1 serves to guide the air in the direction of the arrows shown to the left, from the blower B to the space between the wall of the receptacle I and a cylindrical casing 9, placed therein and resting on legs Ill.

The casing 9 has along its upper edge a sealing gasket I2 against which a removable cover I3 rests during the washing periods. This cover I3 has a central, countersunk part I4 the shape of which roughly corresponds to the shape of part 8, and in order to keep a suitable space between the two parts, part 8 carries a, breast-ring I6, resting against the central part I4. The part 8 has at its middle an opening IT, for the flow of air to the blower 6, which opening I! is protected against spray from the inner wall of the receptacle by means of a guard-plate I8, formed in the central part I4, and provided with air vents I! along its circumference.

During the washing periods the casing 9 is filled with water and articles to be washed, through which the circulating air bubbles, and as long as the blower 6 is kept going air will flow along the course indicated by arrows in Fig. 1 of the drawings.

When the articles are to be dried, the water is drained from the receptacle I through a bottom cock II, and the cover I3 and the casing 9 with the articles are removed from the receptacle I. In order that the casing 9 may serve as a clothes basket in this operation, it is provided at its bottom with a removable perforated plate 20. Then a tripod 22 with a post 23 carrying a hydro-extractor drum 24 is inserted in the receptacle I, and when the machine is subsequently closed and the blower 6 started the air will flow along a course indicated by arrows in Fig. 2 of the drawings, 1. e. the air will now pass from the blower 6 against radial vanes 2I on the upper edge of the hydro-extractor drum 24. and the air will return to the blower 6 after having passed around the circular side of the drum 24 and up through holes 25 in the inner wall 28 of the drum 24.

Thereby the drum 24 will be rotated at high speed and the water in the articles will be flung out and will be drained off through a slit 2'! in the drum.

When the machine is not in use (Fig. 3) the hydro-extractor drum 24 may be placed inside the casing 9 in the receptacle I, when its loose bottom plate 20 has been removed and placed at the bottom of the receptacle I.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

In a machine for washing articles, the combination of a receptacle; a casing dimensioned to provide a space between said receptacle and said casing and having air ports in its bottom, said casing being non-rotatably disposed in said receptacle during washing; a removable cover for said receptacle; a plate mounted on the under side of said cover and comprising a depending frusto-conical perforated portion and a flat peripheral imperforate portion; a fan carried by said cover, concentrically of said perforated portion and adapted to induce a radially flowing current of air through said perforated portion and under said imperforate portion; and a second plate adapted to be removably mounted on said casing in air-tight relation and comprising 2. depending frusto-conical imperforate portion, a perforated portion depending from said imperforate portion and a flat peripheral im- 4 perforate portion about said frusto-conical portion, the parts being so shaped and dimensioned that, when said casing and its plate are in said receptacle and said top is on said receptacle, said perforated portion of said first plate is in said depending imperforate portion of said second plate and bears on said imperforate portion of said second plate adjacent said perforated portion of said second plate and the fiat peripheral portions of the two plates are in parallel spaced relation, thereby forming a channel for passage of air from within the casing through the perforated portions of the two plates and between the two fiat portions to the space between the receptacle and the casing.
